image url can't be get from firebase storage to firestore database

I tried to store image to firebase storage and try to get an image URL to the database these are the codes. this is the code that I used to upload the image to firebase storage.

   uploadNotice()async{

   String fileName=basename(noticepic.path);
  final StorageReference firebaseStorageRef=FirebaseStorage.instance
  .ref().child('cisnotices/$fileName');
    StorageUploadTask task = firebaseStorageRef.putFile(noticepic);
    var dowurl = await (await task.onComplete).ref.getDownloadURL();
    var url=dowurl.toString();
    noticeProvider.changePhotoUrl(url).then((val){
        print('photo url got');
      }).catchError((e){
        print(e);
      });



}
NoticeProvider noticeProvider=NoticeProvider();

here is the noticeprovider.dart I used to change the image URL 

class NoticeProvider with ChangeNotifier {
  final firestoreService=FirestoreService();

 String _noticeId;
 String _userName;
 String _userPost;
 String _date; 
 String _photoUrl;
 var uuid=Uuid();

 //getters

 String get userName => _userName;
 String get userPost => _userPost;
 String get date => _date;
 String get photoUrl => _photoUrl;

 //setters

  changeUserName(String value){
  _userName=value;
 notifyListeners();
 }
  changeUserPost(String value){
 _userPost=value;
  notifyListeners();
 }
  changeDate(String value){
  _date=value;
  notifyListeners();
}
 changePhotoUrl(String value){
  _photoUrl=value;
  notifyListeners();
}

 saveNotice(){
  var newNotice=Notice(userName: userName,userPost: userPost,photoUrl: photoUrl,
  date: date,noticeId: uuid.v4());
  firestoreService.saveNotice(newNotice);


 }



 }

here is firestoreservice.dart

  class FirestoreService {
 Firestore _db=Firestore.instance;

  Future<void> saveNotice(Notice notice){
     return _db.collection('notices').document(notice.noticeId).setData(notice.toMap());
  }

  }

image is saved in firebase storage, but the URL can't get to the database. it always shows 'null'.

Try this one to upload image/File and get it's Download URL

 final StorageReference storageReferencem = FirebaseStorage()
      .ref()
      .child("Users/${DateTime.now().millisecondsSinceEpoch}");
  final StorageUploadTask uploadTaskm =
  storageReferencem.putFile(croppedFile);
  await uploadTaskm.onComplete;
  await storageReferencem.getDownloadURL().then((url) {
    URL=url;
  });
